Mountains are where the DT12 and Detroit integrated drivetrain really shine. The truck has extensive maps of not just location but also topography. The truck knows where it is, what grade the road is, and what the road looks like ahead. Using this information it can optimize shift points both uphill and downhill. The front radar also tells it if there is traffic ahead

It is really hard for a human driver to beat a computer in these conditions. They would have to know the road by heart.

EDIT: Max torque is also lower - @ 975 RPM - so that likely explains it shifting at different RPMs than you are used to with a conventional manual.
